In Romania, theology student Allison has come into possession of The Lexicon, a mysterious book of prophecies that writes itself. This book contains a 23rd chapter of the Book of Revelation, which is still not complete. The last chapter depicts the end of the war of angels and the name of the Antichrist. One of the angels who fell with Satan, Belial (now a demon), wants this book. Simon, a good angel, opposes him and guides Allison by taking advantage of her mental illness to speak directly to her. While searching for Allison and the book, and to avoid detection, Belial murders people and takes their form.
